摘　　要：为了减小舰艇水下静电场,提出了阳极极化与阴极极化相结合的电位平衡方法。首先,通过检测船体-螺旋桨电位差,利用塔菲尔公式计算了船体阳极极化电流和螺旋桨阴极极化电流,并使用辅助电极输出极化电流,使船体-螺旋桨之间的电位差降到0V左右,实现了电位平衡,因此无腐蚀电流产生,与之关联的水下电场也将得到了消除;然后,将此方法应用于船模实验,结果发现船模水下静电场降低70%以上,由此表明该方法能较好地实现静电场防护的作用。In order to reduce the electrostatic field values of ship,the method combining the anode polarization of hull with the cathode polarization of the propeller is proposed to reduce the potential difference between the hull and propeller to 0 V.At the same time,there is no corrosion current between the hull and propeller,and the associated electrostatic field is also eliminated.It is proved that through this method the electrostatic field of the ship model can be reduced and the effect of electric field protection by the potential balance experiment of the ship model can be achieved.
